Respuesta :
When nitric oxide gas is dissolved in an aqueous solution then releases a hydrogen ion that makes the solution acidic as nitrous acids are formed. Thus, option b is correct.
What is an acid?
An acid is a chemical that releases hydronium or the hydrogen ion when they are dissolved in the water causing the formation of the salts along with it. They are chemicals capable of donating electrons.
These substances completely or partially dissociate the hydrogen or the hydronium ion in the water along with salt and are called strong and weak acids, respectively. On the other hand, the release of the hydroxide is the characteristic of the base.
When nitric oxide dissolves in water, the reaction occurs as,
4 NO + O₂ + 2 H₂O → 4 HNO₂
Here, nitrous acid is formed by the release of the hydrogen ion.
Therefore, an acidic solution is formed.
